Did a bit of track and accumulate ( short exposure 15-20 sec ) imaging again the other night with my ST2000XCM.

They're results to be happy about :thumbsup:

yep youve mastered 20 sec exposures,.... i would like to see a guided image with that ccd camera:)

Two very nice captures Steve.

Well done.

hey steve. great shot mate esp M42. you having a ball with that ST2000XCM

Eta! Haven't seen her for a while! Nice results for short exposures, Steve.

Cheers Roger !



So would I Al !



Thanks Ric !



It's coming along slowly Eric ! Got to get the guiding happening then the images should really improve I hope !



Thanks Mike ! Eta is still rising a bit too late at this stage ay so I took this image at the end of my session around 4-5am. It should get better as Summer progresses and it gets closer to the meridian, especially from where I am situated regards light polution.

THANKS ALL FOR YOUR COMMENTS !

Very good results with short exposures like this.

What's happening here Steve? :shrug: Don't mean to be blunt, but mate, you've got a killer camera capable of self-guiding - get it working for you. Auto guide to go deep and get those 10-15min subs to better your signal to noise ratio.

The signal to noise ratio of a CCD increases linearly with the square root of the exposure time. This means that quadrupling the exposure time doubles the signal to noise ratio. So take the longest effective exposure you can. This applies to all forms of CCD imaging, but is especially important for narrowband imaging where filters restricted the quantity of light reaching the chip.

The sooner you sort out your guiding woes, the better. Look forward to seeing new developments:thumbsup:

nice results for such a short exposure

Cheers Mill !

I don't know why the self guiding won't work as yet Jase ..... it may just be a cabling problem ..... I know the St2000XCM camera is a very capable piece of equipment that's why I bought it to significantly upgrade from my 350D and to be able to auto guide .... I've seen some wonderful images with it taken by other people !
